Sean Rector, the 30-year-old teacher from Harlem, New York, became the latest contestant voted off Survivor: Marquesas Thursday night. "I just know that, through it all, it's been a blast," he said after learning his fate. "I am just a humble young man trying to find my way through the world. God bless America." The ultimate Survivor will be crowned during Sunday night's two-hour finale (8 pm/ET). But the secret is already out: Rosie O'Donnell — who will emcee Sunday's live Survivor reunion (10 pm/ET) — announced on her talk show today that she has already seen the final episode and knows who wins.
